Portuguese neighbour welcomes recipe that comes with a twist (6)
I believe the answer is:
sprain
'twist' is the definition.
(sprain is a kind of twist)
'portuguese neighbour welcomes recipe that comes with a' is the wordplay.
'portuguese neighbour' becomes 'spin' (I can't explain this - if you can you should give a lot more credence to this answer).
'welcomes' indicates putting letters inside (in sense of 'invites in').
'recipe' becomes 'r' (abbreviation).
'that comes with' means one lot of letters go next to another.
'r'+'a'='ra'
'spin' placed around 'ra' is 'SPRAIN'.
Can you help me to learn more?
(Other definitions for sprain that I've seen before include "Wrenching (of a muscle)" , "Wrench; in rasp (anag.)" , "Injury to the ankle, say" , "sign of strain" , "Wrench a joint" .)
